Application filed March 11, 1904. Serial No. 197,668-

- theobjects of the invention is to provide eflicient means for readily connecting and disconnecting the type-bars and their actuating means.

A further object of vmy invention is to provide simple and eflicient means for preventing dust, grit, or rubbin'gs which may-drop from the'paper at the front face of the platen from entering the pivotal bearings 'of the type-bars.

A still further object of my invention is to provide simple and efiicient means for connecting the type-bars to their actuating sublevers or devices by links, which-will afford a turning movement or adjustment of one end of a link relatively to the other end thereof, so that pivotal axes at opposite ends of each link may lie in planes that are at angles to each other.

To the above and other ends, which will be hereinafter described, my invention consists in the features of construction, arrangements of parts, and combinations of devices to be hereinafter described, and particularly pointed out in the-appended claims.

In the accompanying drawings, wherein like reference characters designate like parts in the various views, Figure 1 is a fragmentary front to rear vertical sectional view of sufficient number of parts of one form of type-writing machines to illustrate my invention in its application thereto. Fig. 2 is a fragmentary transverse sectional view of the same, the section being taken on the line 00 9c, of Fig. 1 and looking 1n the direction of the arrow at said line. Fig. 3 is a plan view of the same. Fig. 4 is an enlarged detail fragmentary side elevation showing the rear or pivotal end of one of the t e-bars. Fig. 5 is a plan view of the same. ig. 6 is a detail plan view of one of the retaining-springs. Fig. 7 is a transverse sectional view of a typebar, the'section being taken on the liney y of row at said line. Fig; Sis an enlarged detail plan view of one of the connecting-links. Fig. 9 is an end view of the same looking toward the front end of the link, and Fig. 10 is an enlarged detail longitudinal sectional View throughthe rear or pivotal end of one of the type-bars.

The base 1 of the machine is provided with Fig. 4 and looking in the direction of the arcorner-posts 2, which support a top plate 3.

.Key-levers 4 are pivoted at 5 in the base and are each provided with a finger-key 6 and a restoring-spring 7. Each key-lever has a sublever 8 pivoted thereto at 9, and the lower end of each sublever is slotted at 10 for the reception .of a fixed fulcrum-bar 1 1, which extends beneath the key-levers from side to side of the machine. The upper end of each sublever is pivoted at 12 to aforwardly-extending link 13, and each link is made of a plurality of parts or members a b, that are united by a threaded or similar connection 14, so that the members of each link are adapted to turn one relatively to the other on their longitudinal axes. ber a is provided with internal screw-threads that cooperate with the external screwthr'eads on the member I), and the forward end of each socketed member is bifurcated at 15, and a rivet 16 is connected to and extends between the arms formed by the bifurcated portion, so as to constitute a pivotfor connection tothe associated type-bar.

Each upwardly and rearwardly striking type-bar 17 is rovided with a plurality of types 18 and is ifurcated at its rear or piv otal end, as indicated at 19, and'the cheekplates 20 of the bifurcated portion are apertured at 20 for the reception of a rivet 21.. A type-bar hanger 22 has its bearing portion received Within the bifurcated portion 19 and between the cheek-plates 20 of the typebar, and the rivet 21 extends through both cheek-plates and through an opening in the type-bar hanger, so as to unite the type-bar and hanger. Each hanger may be secured in a slot 23 in a segment 24 by means of a setscrew 25, that is received in a threaded opening in the forward face of the segment and passes into an aperture or recess 26 in the type-bar hanger. A restoring-spring 27 is connected at one end 28 to the type-bar and at its other end 29 to the associated type-bar hanger. Extending upwardly from each type-bar is a hook or engaging member 30, the hook opening forwardly, as represented in Fig. 4. A leaf-spring 31 has an elongated aperture 32 therein to enable the spring to straddle the hook, as represented in Fig. 4. This spring is likewise apertured or recessed at 33 for the reception of lugs or studs 34, which project upwardly from the type-bar and are preferably formed integral therewith, and these studs are bent over the body of the spring at their upper ends, as represented in Figs. 5 and 7, in order to secure the spring at one end to the typebar in the rear of the engaging hook 30. The looped end of the member a of each connecting-link 13, formed by the bifurcated portion and rivet, is adapted to straddle the engaging hook on the type-bar, so that the rivet or pivot 16 is seated Within the bill of the hook to connect the type-bar to its actuating means. The

retaining-spring 31 is adapted to bear at its free end against the forward end of the associated link and to prevent an accidental disengagement between the link and the engaging hook of its associated type-bar, at the same time enabling a disengagement between the parts to be readily effected when desired. 7

From an examination of Fig. 10 it will be observed that the retaining-spring 31 extends over and constitutes a top wall or coverplate for the bifurcated portion 19 of the type-bar, to which the spring is connected, so as to cover the pivotal joint between the type-bar and hanger and to prevent the admission of any dust, grit, or rubbings which may drop from the front face of the platen 35 or the paper thereon, which is above and in a plane substantially coincident with the pivotal bearings of the type bars. The

platen is diagrammatically illustrated in Fig.

1, and it may be mounted in a suitable carriage (not shown) that is adapted to travel from side to side of the machine in the usual manner.

From an inspection of Figs. 2 and 3 it will be observed that the type-bar segment 24 is provided with grooved tracks 36, that receive 'antifriction balls or rollers 37, which are likewise received in grooved tracks in the upright guides 38, so as to aflord a vertical shifting movement of the segment to effect a relative shift between the type-bars and platen in order to bring either upper or lower case types into use. It will be observed that the construction of the sublevers, link connections, and themanner of attaching the same to the type-bars afford a shift of the type-bar segment in order to change the case position thereof without affecting the operation of the individual type-actions.

From an examination of Figs. 1, 2, and 3 it will be seen that the key-levers 4 at those portions thereof where the sublevers are connected to them are parallel, that the upright sublevers are parallel and terminate at their upper ends in an are which is substantially coextensive with the arc in which the typebars are situated, that the links 13 are hori- Zontally disposed and are likewise situated in an are which is substantially coextensive to the are in which the upper ends of the sublevers and the type-bars are located, that said links or actuating devices 13 extend forwardly from the sublevers to the type-bars in straight lines that extend fore and aft of the machine, that the links which unite the sublevers and type-bars at the sides of the system each have an end which is connected to its sublever and which is located in a vertical plane, and that the forward end of said link is situated in a plane that extends at an angle to said vertical plane and corresponds to the plane of movement of the associated type-bar. In other words, it will be understood that the axis of the pivotal connection between a link and type-bar at a side of the system is at an angle to the axis of the pivot which unites the opposite end of said link to its sublever and that these angles increase gradually from the center to the sides of the system. By making the links of a plurality of parts or members in the manner shown and described, so that one end of each link may be turned on its longitudinal axis relatively to the other end, a construction is provided which enables a uniform character of link to be used throughout the system and without bending the individual links to provide for the difference in the planes of movement of the different individual sublevers and type-bars and the difference in the angular relation of the pivotal connection of the links. Furthermore, it will be understood that this construction affords means for readily assembling the parts without the liability of effecting any lateral or torsional or twisting strain between the parts in the operation of the machine, as is sometimes the case where single-piece links are employed. The threaded connection between the members of the two-part links likewise enables a shortening or lengthening of the links to be effected, so as to take up and compensate for any undue lost motion that may be present throughout the action, and to enable all of the type-bars to be properly brought to rest in the basket.

In order to connect an actuating-link to its associated type-bar, it is merely necessary to slightly elevate the forward end of the bar, so as to enable the pivot 16 of the link to be forced within the bill of the hook by pressing the retaining-spring 31 against its tension. As soon as the pivot 16 is seated within the hook the spring may be freed and will maintain a roper engagement between the parts and wi prevent an accidental disconnection between the type-bar and its actuating link or device 13 and inthe operation of the machine the pressure exerted by each link is against the rear or closed portion of its hook and tends to maintain the pivot 16 seated in the hook. A disengagement ofa link from its associated type-bar may be effected in a like manner by first sli end of the type-barand then depressing. the

forward end of the link to overcomethe tension of the retaining spring 31, when the pivot may be withdrawn from the bill of the k and'the type-bar and link thus disconnected, and, if desired, the'type-bar, its associated hanger, and restoring-spring may then be remove from the machine as an entirety by partly withdrawing the set screw 25,

which maintains the hanger in place in the se ment.

arious changes may be made without departing from the s irit of my invention, and certain features t ereof may be employed without others.
